Specification of Letters Patent. Patented Aug, 15, 1922,

Application filed February 17; 1921': Serial No. 445,711.

To all whom it may concern. v

Be it known that I, FREDERICK Roonwoon BANKS, a citizen of the Umted States, and

a resident of Paterson in the county of Passalc and State of New Jersey, have 111. vented a new and Improved Valve Hand,

wheel, of which the following is a full, clear, and exact description. 1

The invention. relates to valves, notably gate valves operating under high pressure.

The object of the invention is to provide invention consists of certain novel features of construction as hereinafter shown and described and then specifically pointed out in the cla1ms.

A practical embodiment of the invention is represented in the accompanying drawings forming apart of this specification, in which similar characters of reference indicate corresponding parts in both views.

Figure 1 is a plan view of the improved valve handwheel with a portion shown in section; and

Figure 2 is a side elevation of the same. In manipulating a gate valve, notably one that is under'high pressure it is frequently necessary for an operator to use considerable physical force in turning the valve handwheel for seating or unseating the valve owing to the high pressure exerted against the gate of the valve. In order to enable the operator to readily turn the handwheel without increasing the diameter of the wheel the following arrangement is made: The hub 10 of the valve handwheel is provided with a square and preferably tapering opening 11, although any form of opening may be used for attaching the valve handwheel to the stem or stem sleeve of the valve, and from the hub 10 radiate integral spokes 12 'rim13.

Although Ihave shown'a socket 14 in connection with each spoke 12 of the handintegrally connected at theirouter ends with a mm 13. As shown in the drawings, sockets 14 are disposed radially and formed partly and integrally on the rim 13 and partly and integrally on the outer end of the spokes 12. The sockets 14 are open at" their outer ends at the peripheral face of the rim 13to permit-"the insertion of a rod or other leverage extension member 15 to allow the operator to readily turn the valvehand wheel with an increased leverage thereby requiring the exertion of considerably less physical force on the'part of the operator 5. for turning the handwheel and for seating i and unseating the valve. Eachisocket 14 is;

a goodsizedextension member and the socket is of sutficient length for the extension mem-' ber 15 to have a secure hold in .the socket wvhen inserted therein: The socket 14, furthermore tends to reinforce the connection between the spokes 12 and the rim, 13. and without requiring increasing of the cross sectional areas of the spokes 12 and the wheel this arrangement is not absolutely necessary as less sockets can beusedif de- I sired.

claim as new and desire to secure by Letters being providedwith radial sockets open at. the peripheral face of the rim for the insertion of a leverage extensionmember with which to turn the wheel saidsockets extendingintothe respective spokes. 1

2. A handwheel for high pressure valves comprising a hub having attaching means for attaching it to the valve member to be turned, spokes radiating from the said hub,

a rim integral with the outer ends of the said spokes, and radially disposed sockets formed-integrally and partly on the said rim and partly and integrally on the outer ends of the said spokes, the said sockets being open at their. outer ends the peripheral face ofthe said rim. I
